STAKING DEVICE FOR ROAD-RAILS.

Specification of Letters Patent.

Patented Aug. 10,1920.

Application filed January'av, 1920. serial No. 354,351.

T0 all whom t may concern:

Be it known that I, MARK S. HorcHnIss, of Binghamton, in the county oi Broome,` in the State olf New York, have invented new and useful Improvements in Staking Devices for Road-Rails, of which the follow ing, taken in connection with the accompanying drawings, is a full, clear, and eX act description.

rl'his invention relates to certain improvements in forms for supporting concrete and analogous materials while in a green state during the process of construction and is particularly useful in forming the edges of sidewalks, road beds and similar work.

The main object is to provide a form, of

this character which may be easily and quickly installed and iirmly held in its operative position with a minimum amount of labor or may be quickly removed and reused in the progressive construction of other parts of the work.

Another object is'to make the form and its braces or stays in separate sections capable of being readily attached to Iordetached from one another so that the main body 'of the Jform may be used to support different parts of the concrete work without or with dili'erent forms of stays. i

A further object isto enable the same braces and stays to be used withdifferent sizes of forms by rendering them relatively adjustable. Y

Other objects and uses relating to specific parts ol the apparatus will be brought out in the following description.,

In the drawings: u

Figure l is a longitudinal sectional view oit' the preferred form of my'finvention as supporting the upright sections of walks and the like.

Fig. 2 is a perspective View of the same device showing a relatively short length of the main body.

Fig. 3 is a sectional View similar tolFig. l except that the diagonal base plate `is omitted. Y

The Jform shown is adapted to be used for supporting-the upright edges of a concrete body -A-f, such as a sidewalk, pavement or analogous structure and comprises a main body 1 brace plates -2- and -3-, a

brace bar -4- and stake plates n`-5 and G all of which parts are preferably madeV oi sheet metal `although they may be made oi' any other suitable material.

The main body jtpreferably consists of an elongated plate of angular cross sec tion having an upright portion -7- and horizontally extending portions -8- and 9*- constituting' flanges projecting upwardly from the upper edges thereof, the upper flange having its free edge .-10- turned downwardly and is provided with one or more slots ll for the reception or the adjacent end'of the brace plate -2-.

. The lowerhorizontal flange 8- is also provided with one or more slots -12- for the reception of the lower end of the stake plate 5* which passes through similar slots -l3- and lin the brace plates 3and 2*, respectively.

The inner end oi, the brace plate Q is reduced in width to form a tongue l5- and shoulders --l6-` at opposite sides thereof, the tongue -l5- being of substantially the same width as the slot *1lthrough which it passes and is deflected upwardly at an angle to the main portion of the plate -2-- to engage the inner face of the downwardly projecting portion 410- of the `flange 9- while the shoulder 16- engages the outer face of the same ilange.

lVhen the plate 2- is interlocked with the ilange -9- in the manner just described, it is held against endwise movement by the upturned end of 'the tongue l5- and shoulders `l6 and Lmay be easily withdrawn from interlocking engagement with the flange -9- by simply rocking its outer edge upwardly'and then withdrawing the entire plate outwardly, these parts being interlocked' by reversing this operation.

,The brace plate -3-- is hinged at one end to the plate 2 by a pivotal pin -17- and extends downwardly and inwardly from the pivot so as to engage the plate '-4- at the junction of the parts -7- and `8- thereby holding the outer end of the plate -2 against downward displacement or rather against overstraining the interlocking parts between the plates -1-4 and f2 and at the same time stiffening the main body -1- of the form.

The` stay rod -4- is also pivoted to the plates 2 and 3* by the same pivotal pin l7 and has its outer end abutting against the stake -G- which latter is vdriven into the ground to establish a firm the work of filling in the concrete against the plate -lprogresses..

, The stake plate 5 is driven downwardly through the vertically registering slots lei- 13- and #-12- and into the ground to further assist in holding the main parts of the form in operative position and at the same time locking the brace plates and -'3 against buckling or flexing at thel joint -17-.

`,The construction shown in F ig. 3 is substantially the same as Vthat shown in Figs. land 2 except lthat the lower brace plate '37- is omitted. It will be evident, however, that when kthe brace plate #2# is interlocked with thevdownwardly projecting portion 104- of the flange -9-, it is supported by said flange against undue downward movement by the engagement of the upturned edge ofthe tongue -15- with the inner face of the part -lO- and the outer face of the same partiso that when thestay bar +4- is placed against the stake A -Gw it will form a continuation of the plate -2- to firmly hold the upper end Y of the plate lagainst outward lateral able it to be easily driven into the ground, the openings as -12-, 13e and lilthrough which it passes being of substantially the same width as that of the stake plate to assist'in holding the main body of the form and otherV parts against relative endwise movement.

It will be noted that the pivotal connection -libetween the brace `plate 2 and the stay bar Ll-fconstitutes a toggle joint which whenthe parts are adjusted for use assumesa substantially straight line to automatically lock these parts in their adjusted positions for pressing the upper' end of the main body f1- against foutward displacement assisted, of course, by the abutting of the outer end of the -bar 44.- against the stake -6. lVhen the concrete has set against the form, thelattermay be removedl fory reuse at another part of the yprogressive structure by simply withdrawing. the stake -5- and flexing the joint w-17-- upwardly which will release the form plate glpand other parts of the mechanism which may then be carried to another part of the work for reuse, it being understood that the stake -6- may or may not be removed,l although the same or another stake will have to be driven into the ground at the place where the form Vis to be installed.

What l claim is 1. A form for concrete and analogous work comprising a main plate having an upright wall and outturned flanges along its lower and upper edges, a slotted brace member engaged with' the inner and outer faces of the 'upper flange and a stake passed through the slot in said brace member and adapted to be driven into the earth.

2. A form for concrete and analogous workcompris'ing Va plate having an lupright wall against which the concrete is adapted to abut, said plate having its upper edge provided with an outturned slotted flange, means for holding the lower edge of the plate against outward movement and additional means having a portion thereof passed through the slot in the upper flange and en-V gaged with lthe inner and outer faces thereof for holding the upper portion of the plate against outward displacement.

3. A form for concrete and analogous work comprising a plate having an upright wall and .outturned slotted flanges along its lower `and upper edges, means including a brace plate passed through the slot in the upper flange and engaging the inner and outer faces thereof for holding the upper portion of the first named plate against outward movement, said brace plate having a slot in Vvertical alinement with that of the lower flange and a stake passed through the slots in the brace plate and lower Vflange and adapted vto be driven into the earth for additionally holdingy the main plate against outwarddisplacement.- Y

4.*A form for concrete` and analogous work Vcomprising a main plate having an upright wall against which the concrete is adapted to rest, means for holding thelower edge of the mainV plate against outwarddis placement, a stake adapted to be drivenlinto the ground some distance from the main plate and ktoggle lconnections between said stake'and upper portion of the main plate for holding said upper portion against outer ing theirinner ends engaged respectively with then lower and upper portions of the main plate andthe other remaining portions disposed in Voutwardly converging planes and hinged to each other at their line of intersection, a stake adapted to bedriven in the ground some Vdistance from the main plate and a brace bar between the stake and pivotal connections between the brace plates.

7. A form for concrete and similar work comprising a main plate having an upright wall and outwardly projecting slotted `lianges, slotted lower and upper brace plates disposed at an angle to each other and hinged together at said angle, the lower brace plate being engaged with the lower portion of the main frame, the upper brace plate passing through the slot in the upper llange and engaged with the inner and outer faces thereotl and a stake passed through the slots in both brace plates and lower flange adapted to be driven into the earth.

8. A'orm for concrete and similar work comprising a main plate having an upright wall and outwardly projecting slotted flanges, slotted lower and upper brace plates disposed at an angle to each other and hinged together' at said angle, the lower brace plate being engaged with the lower portion of the main frame, the upper brace plate passing through the slot in the upper flange and engaged with the inner and outer faces thereof and a stake passed through the slots in both brace plates and lower flange adapted to be driven into the earth, a stake adapted to be driven into the earth some distance from the main plate and a brace bar interposed between the last named stake and pivotal connection between the brace plates.

In witness whereof I have hereunto set my hand this 17th dav of January, 1920.
